Zone Refining

A method of purifying a bar of metal by passing it through an induction heater, this causes impurties to move along a melted portion. This method applies the fact when a metal crystallizes on cooling, impurities are automatically expelled as they do not form part of the crystal.

Linkage Isomers

Isomers in which a particular ligand bonds to a metal ion through different donor atoms.

 

Pairing Energy

Energy required to pair two electrons in the same orbital.

Reverse Osmosis

Forcing solvent molecules to flow through a semipermable membrane from a concentated solution into a dilute solution by the application of greater hydrostatic pressure on concentrated side than the osmotic pressure opposing it.

PseudobinaryIonic Compounds

Compounds that contain more than two elements but are named like binary compounds.

Spectator Ions

Ions in a solution that do not participate in a chemical reaction.

Dermal toxicity

Adverse health effects resulting from skin exposure ot a substance.

Saccharate

A compound formed by interaction of sucrose with a metallic oxide, usually lime, and useful in the purification of sugar.

 

Voltaic Cells

Electrochemical cells in which spontaneous chemical reactions produce electricity, also called galvanic cells.
